DOFFING APPARATUS FOR PICKING OR GINNING MACHINES SPECIFICATION forming part of Letters Patent No. 337,014, dated March 2, 1886.

Application filed November 21, 1885. Serial No. 183,503. (No model.)

To aZZ whom, it may concern,-

Be it known that I, STEPHEN R. PARK- HURsT, of Montclair, in the county of Essex and State of New Jersey, have invented an Improvement in Doffing Apparatus for Picking or Ginning Machines, of which the following is a specification.

In my Patent No. 56,675 a brush is represented for removing the cotton or other fiber from the toothed cylinders, and a pair of cylinders of wire-netting catch the fiber, but allow the air from the brush to pass away.

My present invention is for arresting the wool or other fiber as it is thrown oft by the brush or picker cylinder or gin, and for concentrating the same into a hat or sheet, thereby saving the risk of fire that exists in the lint-room, and lessening the space required. At the same time I oil the wool while in the loose and open condition in which it leaves the brush or cylinder.

In the drawings, Figure 1 is a section transversely of the clotting cylinder and parts made use of at the end of the delivery trunk or spout; and Fig. 2 is a partial section longitudinall y of the dofi'er-shaft atone end thereof, showing the bearing and driving gear and pulley in plan View.

The spout or trunk A, through which the wool, cotton, or other fiber passes as projected by a brush or cylinder from the toothed picker or gin cylinders, usually has an upward inclination. I terminate the spout or trunk by a nearly circular case, 13, within which is the hatchel-tooth doffer or delivery cylinder O. This cylinder 0 is made of open heads d, be tween which are tubular bars 6, each of which is provided with a row of holes along the side that stands outwardly. These holes are filled with wire teeth 2', that are pointed at their outer ends, similar to hatchel-teeth, and the inner ends strike against the opposite inner surfaces of the tubes-when driven in; hence this cylinder 0 has an exterior formed of radially-projecting teeth from an open frame, and this cylinder 0 is rotated by competent power and at a comparatively slow speed within the case B and in the direction of the arrow, Fig. 1, so that the wool, cotton, or other fibers thrown off by the centrifugal force of the picker, gin-cylinder, or brush are impaled upon the teeth 1', and thereby caught and retained, while the air passes through and escapes at the ends of the case B. The wool or cotton is carried down by the rotation of the cylinder 0, and the accumulation will pack the teeth full, or nearly so, at the place where the wool or cotton is carried down inside the curved case B.

The delivery-roller K is below the cylinder 0, and is upon a shaft in fixed bearings, and it is preferably of wood. Above this roller K is the roller L, that is preferably of iron, and its shaft is in vertically slotted or open bearings Z, so that this roller L is free to rise and fall. The roller K may be driven by a belt, K, from a pulley on the shaft N.

The bat or sheet of wool or cotton is drawn off the teeth of the cylinder 0 and passed be tween the roller K and the roller L, and as the movement given to these rollers K L is considerably faster than that of the cylinder 0, the fiber is pulled off in a sheet or bat and delivered.

The roller L adapts itself to inequalities in the bat, and it is of sufficient weight to consolidate the bat sufficiently as it is drawn ofi.

The shaft N of the cylinder 0 is preferably tubular, and to it the heads are permanently attached, and at O the bearing for the shaft is shown, and P is the driving pulley or gear. This shaft N is perforated at suitable places within-the cylinder 0 for the passage of oil for oiling the wool, and beneath the shaft hangs the distribution-trough Q, suspended from the shaft by the straps 1', and to the tubular shaft oil is supplied,preferably at both ends and in a regulated quantity, by the pipe S, and the coupling T,ofany suitable character,scrves to connect'the oil-pipe to the tubular shaftN and prevent waste of oil.

The oil employed is adapted to the oiling of the wool. It enters by the pipe S and runs into the distribution-trough and overflows from its edge, and this oil drops upon the wool previously to the bat being drawn off the teeth, and said oil spreads with uniformity through the bat by capillary action.

If desired, steam may be supplied through the pipe and tubular shaft in place of oil, so

as to warm and moisten the wool or cotton; or both steam and oil may be supplied at the same time.

I claim as my invention 1. The combination, with the delivery spout or trunk of a picking or ginning machine, of a case, and an open cylinder provided with projecting teeth within such case, a delivery-roller below the said cylinder, and a movable roller for drawing the bat of Wool, cotton, or other fiber off the teeth, substantially as set forth.

2. The combination, with the deliverytrunk and a case at the end, of the open cylinder provided with projecting teeth for catching the wool, such cylinder being composed of heads, with tubular bars between the heads, and teeth inserted into holes in such tubular bars, substantially as set forth.
